Don't try to hide your addiction to singing in the shower — embrace it with the Kohler Moxie Speaker Showerhead ($150). This clever piece of bathroom hardware embeds a speaker in the middle of a full-spray showerhead. And not just any speaker — a Bluetooth-compatible speaker that lets you recharge it on the counter, snap it back into the showerhead using the embedded magnets, and play music wirelessly from your phone or tablet. Just don't forget to clean yourself up while you're at it.
